IM-CONNECTOR FOR ELECTRIC CONDUCTORS.

To all whom it may concern: a y

Be it known that I, Monms F, FINKEL- s'rsiN, a citizen of the United States, and

a resident of the city of New York, borough ductor can be electrically connected with a p as cable or main conductor.

The invention has for its general objects to improve the construction and o eration of devices of this character so as to e reliable and eficient in use, comparatively sim 1e and inexpensive to manufacture, and so esigned that electrical connection can be easily and quickl made.

A more speci c object of the invention is the provision of a novel means for bind: ing the connector to the cable in a simple, reliable and effective manner.

A further object is the provision of an improved clip or clamp arranged within the body of the connector and-adapted to re- .ceive the end of the branch wire which is securely held by the clamping screw whichbinds the clamp or clip on the said wire.

With such objects m view, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with partilcularity in the following description and claims appended hereto.

In the accom anying drawings, which illustrate one em odiment of the invention and wherein similar characters of reference indicate corresponding parts in all the views,

Figure 1 is a longitudinal section of the connector in use;

Fig. 2 is a transverse section on the line 2-2, Fig. 1;.

Fig. 3 is a perspective removed. p

Referring to the drawing, A designates a main wire' or cable, B a branch wire or cap, and C the connector.

The cableA has a portion of its insulaview of the clip tion 1 removed at 2, so that the connector can be boundto the of the cable and Specification of Letters Patent. 7 application filed May as, 1917. Serial at, 170,170.

electrically connect therewith. The branch wire Bhas its end 3 bared of insulation and clamped in the connector C.

The connector C comprises a tubular body 4 of steel or other metal, the ends of the tube being open. 3 In the-tubeis a clip or clamp 5 made of'a stri of brass or other'metal and doubled to orm a sprin member 6 which lies over the body mem er 7. This clamp is held in place b being extended into a base member 8 whic is doubled backwardly so as to lie outside the tubular body a. The members 7 'and 8 engage the same wall of the body but the-inner and outer surfaces respectively, and the extremity of the base member 8 is bent perpendicularly into a lug- 9 which enga es in and closes he mouth 10 of the clamp or cli faces in the direction of the open end 0 the body 4 so that the branch wire 3 can be inserted in the open end. of the connector body and be engaged between the clam members 6 and 7. The

base member 8 is ound directly against the strands of the cable so that a good electrical connection will be 0 tained between the cable and the'branch wire. The branch wire is securelyclaniped by means of a set-screw 11 which is threaded in an opening 12in the body 4, the inner end of the screw bearing on the member 6 so as to move the same toward the member and thereby clamp the branch wire between such members. In this I manner the branch wire can be easily and quickly connected or disconnected, it being merely necessary to tighten or loosen the screw 11.

The connector is bound to the cable by means of a plurality of bands 13 which pass around the cable and thebody 4, as clearly shown in Fig. 1, the ends 14: of each band being overlapped so that the apertures 15 in the said'ends will register and engage with a stud 16 formed b reducing the outer end of the screw 17 which engagesin the tapped opening 18 of the ing the screws 17 inwardly the bands 13 can be loosened so that their ends can be disengaged from the studs 16 for removing the connector from the cable. In applying the connector to the cable the bands are wrapped around the cable and body of the connector, and after the ends of the bands body 4:. By turn-.

tending arolmd the main wire and body with its ends overlappingand having openings in e the stud of the screw,

17, the screwsare turnedin a direction to work them outwardly so as to; thereby tighten the bands and clamp the connector tothe conductor. 5 From the foregoing description taken in connection with the accompanying drawings, the advantages'of the construction and method of operation. will be' readily under- Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. The. combination of a main wire, a branch wire and a connector for uniting the wires, said "connector including a ho a screw threaded therein and formed withastud on its other: end, and a binding member exits ends to enga whereby the turmng of the latter in one direction loosens the band and in, the other direction tightens the same.

2. The combination of a main wire, a branchv wire and a connector the wires, said connector including a tu ular body, a clamp therein including a yieldin member extending lengthwise of. the sai body gaged, and

into contact with thebranch wire, saidclamphaving a member'ex tending out of the body body and'lying'between and and with which the branch ;.wire is en-; ascrew in the body bearing on. the yielding member'for jamming the sameand lying between and in contact with the main wire and said'body, 7 V

4. The combination of a main wire, a branch wire and a connector' unitin the wires, said connector including a tuiular 65 "body, a clamp therein including a'yielding member with which the branch wire is engaged, and a screw in the body bearing on the'yielding member for jamming the same into contact with the branch wire, said clamp having a member extending out of the in contact with the main wire and said body, the extremity of the said member being bent outwardly to engage the end of the body opposite from that into which the branch wire extender 5. A connector of the class described comprising a tubular-body, a clamp formed with a doubled extremity lying within the-body and having a portlon extending outside the 7o body and lon tudinally thereof, and a de-. vice adjustab y mounted on the body and- -engaging the said doubled portion for clamping the same to a wire. H 6. A connector of the class described comprising a tubular body having one wall provided with a plurality of threaded openings, a clamp in. the body for receiving a branch wire, a screw engaging in one opening and adapted to screw inwardly to tighten the clip to the branch wire, bands for binding the bod to a main wire, and screws enga ing in t e other 0 enings andengaging wi the bands and a a ted to screw outwardly for tightening the ands.
